## ✅ Write Unit Tests with Jest

### 1. Install test tooling

```bash
npm install --save-dev jest ts-jest @types/jest
npx ts-jest config:init
```

### 2. Example test

Create a file at `test/client.test.ts`:

```ts
import { initOTPClient } from '../src';
import { getClient } from '../src/client';

describe('SDK Client Init', () => {
  it('should initialize Axios client with API key', () => {
    initOTPClient({ apiKey: 'test-key' });
    const client = getClient();
    expect(client.defaults.headers.common['x-api-key']).toBe('test-key');
  });
});
```

### 3. Add test script to package.json

```json
"scripts": {
  "build": "tsup",
  "test": "jest"
}
```
